Hi Josh, I am facing a similar issue as you did sometime back ie. the JBossSecurityMgrRealm instance that is provided to me in my custom valve has a null securityCtx. I am still a newbee to Jboss and JAAS. I could not understand your last post as to which code did you move to the authenticator ? In my case I have only created a custom valve - NO custom authenticator. Can you please help me with this as I have been struggling with this issue for a week now. Thanks, Swati View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135814#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
